The good news is that it is very easy to convert Python lists that are "array-like" to Numpy arrays. A key difference is that the elements of a Numpy array are all of the same type and have a fixed and very specific data type once created. 1 Create a Numpy array . 1.1 You can use the low level constructor ‘ndarray’ to create an array. For ...
